As shown, a pair of spaced arms I are attached to the movablepress head and` extend outwardly therefrom. The arms may be attached inany suitable manner to the press head 5 and any desirable strengtheningbracing. or brackets (not shown) may be utilized. Bars or connectingmembers II carried adjacent their upper ends by the outwardly extendingarms Ill, extend downwardly and are connected adjacent their lower endswith a platform-like part I3. The connecting members Il are shown in thedrawings as round bars but they may be formed of any suitable structuralmembers or the like and may be connected with the platform I3 by nutsI5, by Welding, or in any other suitable manner.

As the press head 5 ascends and descends the outwardly extending arms I0attached thereto serve to raise and lower the platform I3 through theintermediation of the connecting members I I. The length of theconnecting member II is preferably such that when the press head 5 is inits lowered position the platform I3 will be substantially in alignmentwith an adjacent floor surface,and such that when thepress head isfreely elevated a fresh stack of bags or other material may be readilymoved from the platform I3 into the space between the base I and head 5.In this manner stacks of material mai be readily pushed onto theplatform I3 and loaded into the machine.

Preferably the connecting members II are guided during theirreciprocation so that the platform I3 is prevented from freely swingingor banging about. As shown the guiding means comprises structuralmembers I4 having slots or apertures I5 through which extend theconnecting members II. The guiding members I4 may be secured to theadjacent floor by bolts or otherwise. I Y

In operation stacks of burlap bags or other materials to be formed intobales are preferably rst placed on a board 8 which has the -transverselyextending slots 'I therein. The slots -1 are shown facing toward thematerials to be compressed so that straps or wires may be passed throughthe openings in connection with tying the compressed stack together toform a bale. The upper board may be secured to and reeiprecate withthepress head 5. When a stack of thematerial is placed on a supportingboard the board may be pushed onto the upper surface of the platform I3,the press head 5 then being in lowered position. As the press head 5elevates, the outwardly extending arms III lift the connecting membersII, platform I3 and the stack of material 3 to be baled and places theupper surface of the platform I3 substantially level with the uppersurface 2 of the press base I. In this relationship the stack 3 may bepushed off the platform I3 and onto the upper surface of the press base.Thereafter the press head 5 descends and compresses the material forformation into bales. Simultaneously with descent of the press head 5the platform I3 is again lowered to the floor. In this relationshipanother stack of material may be pushed onto the platform I3. When thepress head 5 again raises the resulting. tied or strapped bale on theupper surface 2 of the press base may be pushed from the surface of thepress base to clear it in preparation for receiving another fresh stackof material from the platform I3. rI'hus the lifting device .orattachment; operates entirely automa*- tically as the press head 5ascends and descends.

While the present device is shown at only one side of the press head 5and is particularly adapted to the elevation of stacks of materials forloading onto the press base I, it will be clear that a similar devicemay be provided,v if desired. at the opposite side of the press so thatmaterials compressed and tied into bales may be pushed from the uppersurface of the press base onto theadditional device for lowering. Wherea device is used at each side of the press the device at one side servesto elevate fresh stacks and the device at the other side to lowercompleted bales of material.

The lengths of the connecting members Il, and other dimensions of theattachment device, may of course vary in accordance with the particularpress. If desired each of the depending connecting members may beprovided with threads I9 for a portion of its length to facilitate usewith different presses and under different conditions.

It will be seen that the present invention provides a new and improvedattachment or device for lifting stacks of material up to the level of apress base, the materials being readily pushed onto the upper surface ofthe press base for formation into bales. The device is relatively simplein construction and operation and operates automatically duringoperation of a baling press itself. The device is sturdy in constructionand is well adapted to withstand the rough usage to which it may besubjected.

As various changes may be made in the form,

construction and arrangement of the parts herein without departing fromthe spirit and scope of the invention and without sacrificing any of itsadvantages, it is to be understood that all matter herein is to beinterpreted as illustrative and not in a limiting sense.

Having thus described my invention; I claim:
